STITCH-REMOVING PUNCH.

Specification of Letters Patent.

Application filed June 1, 1908.

Patented Mar. 15, 1910.

Serial No. 435,938.

To all whom it may concern:

Be it known that I, O'r'rnn JOHNSON, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Stitch-Removing Punches;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to improvements in devices for removing the threadsor stitches from the welt of a shoe, before applying a new sole thereto.It is found in practice that it is necessary to remove these stitches inorder that the applying of the new sole may be neatly done.

The object of my improved device is to greatly facilitate the work ofremoving the two stitches from the openings formed by the sewing awl.

My improved device consists of a pair of jaws connected to cooperatewith each other. One of these jaws is recessed at one extremity and theprojecting parts on opposite sides of the recess are adapted to enga ethe layer from which the stitches are to be punched. The other aw isprovided with a punching pin or projection adapted to enter the awlholes and remove the stitches from the welt.

Having briefly outlined my improved construction, I will proceed todescribe the same in detail reference being made to the accompanyingdrawing in which is illustrated an embodiment thereof.

I11 this drawing, Figure 1 is a perspective view of my improvedstitchremoving punch. Fig. 2 is a fragmentary side elevation of the sameshown on a larger scale. In this view a shoe is shown in section, thepunch being shown in position for removing the stitches from the welt.Fig. 3 is a fragmentary detail view of one of the jaws. In thisspecification this will be termed the lower jaw. This is a View lookingin the direction of arrow 3 Fig. 2. Fig. 4 is a similar view of theupper jaw looking in the direction of arrow 4.

The same reference characters indicate the same parts in all the views.

Let the numerals 5* and 6 respectively designate the upper and lowerjaws of my improved tool. These jaws are crossed at their rearextremities and pivotally connected together as shown at 7. Their handlemembers 8 and 9 extend rearwardly whereb the necessary leverage isobtained for per orming the stitchremoving function. The lower jaw 6 isprovided at. its forward extremity with a recess 27 having projections28 on opposite sides thereof, said projections being turned inwardly asshown at 29.

The upper jaw or that designated 5, is provided with a depending stud orpro ection 10 having a reduced free extremity 12 adapted to perform thestitch removing function. The extremity 12 is of sufficient length topass entirely through the welt 13 of the sole, whereby the stitches 1-1are removed. The punch point 12 is arranged to register with the recess27 of the lower jaw. This recess makes room for the ejected stitches,while the members 28 extend underneath the protruding part or welt 13,thus forming a support for the welt during the stitch-removingoperation.

As shown in the drawing, a coil spring 15 is interposed between the twojaws 5 and 6. Each of these jaws is preferably recessed as shown at 17,to receive the opposite extremities of the spring. A short stud or pin18, protrudes inwardly from each jaw to aid in holding the spring inplace. This spring normally holds the two jaws in the open position.

From the foregoing description the use of my improved stitch punch willbe readily understood. Assuming that the outer portion of the sole hasbeen removed, leaving the welt 13 only, the lower jaw 6 of my improveddevice is placed under the protruding edge of the welt after which theupper jaw o is forced downwardly causing the reduced pin extremity 12,to engage the stitch 14. and remove it from the awl hole. It may bereadily moved along the edge of the welt 13, until all the stitches havebeen punched out. Usually these stitches or their parts, will adhere tothe sole but may be readily scraped off.

Having thus described. my invention, what I claim is:

A stitch removing punch, provided with two cooperating jaws pivotallyconnected together, one of said jaws being provided with a recess havinginwardl turned projections upon the opposite si es thereof locntedadjacent its free extremity, the opposite jaw having a stud arranged atright angles and provided with a reduced punch point arranged toregister with the inner portion of the recess in the opposite jaw forstitch removing purposes, the extremities of the recessed jaw extendingconsiderably beyond the punch point to give the tool a firm hold on theWelt, substantially as described. 10

In testimony whereof I nfliX my signature in presence of two Witnesses.
